AUGUSTA, Maine (AP)   Maine’s governor faces a deadline for weighing in on a bill to allow voters to rank candidates in the state’s March presidential primary.

Gov. Janet Mills has until midnight Friday to sign or veto the bill, or let it go into effect unsigned. Lawmakers approved the bill Aug. 26, and Mills has had 10 days to act.

Voters would rank each candidate on a ballot in order of preference. If no candidate gets more than 50%, the last-place candidate is eliminated. The second choices of everyone who ranked that candidate first are distributed, under a process that ends when someone receives over 50%.

Mills told Maine Public this week that she’s carefully reviewing the bill to see how it impacts the general election of electors for presidents.
